Frequently Asked Questions

What is Metastin (Kisspeptin) and how does it work?
Metastin is kisspeptin, a peptide that sits upstream of GnRH in the hypothalamic-pituitary-gonadal axis. It triggers the hypothalamus to release GnRH, which then signals the pituitary to release LH and FSH. This makes it a natural upstream driver of the same hormone cascade that testosterone and fertility depend on, rather than a hormone replacement itself.
How is Metastin typically dosed?
As a guide and not medical advice, a common starting protocol is 100 mcg injected subcutaneously once daily in the morning, with some users running it every other day instead. Total intake is generally kept under 200 mcg per day for a run of 4 to 8 weeks. Reconstitute with bacteriostatic water and keep the vial refrigerated once mixed.
Does Kisspeptin require PCT or extra support?
Kisspeptin does not suppress natural hormone output or bring on oestrogenic side effects, so it does not carry a mandatory PCT requirement on its own. It is often paired with testosterone to help maintain HPG axis signalling through a cycle, or with hCG for a stronger combined LH push.
What side effects are reported with this peptide?
Reported effects at research doses are generally mild, including some injection site irritation, occasional facial flushing, and rare nausea. No serious adverse effects are commonly reported at typical protocol doses, but bloodwork should still be used to track your own response.
Should I check bloodwork while using Kisspeptin?
Yes. Baseline LH, FSH, total testosterone, and oestradiol are worth checking before starting, then repeating around the 4 week mark to see how your HPG axis is responding. If Kisspeptin is used on its own with no other compounds, follow-up bloodwork after finishing is not usually necessary.
